What Cosium does

Cosium SAS, founded in 2003 in Versailles, France, is a privately-held software vendor specializing in Practice Management System (PMS) solutions for optical and audiology professionals. The company develops and operates CosiumOptic (for opticians) and CosiumAudio (for hearing aid dispensers), covering billing via Sesam-Vitale and 100% Santé norms, manufacturer EDI ordering, third-party payer management, patient dossiers, agenda, CRM, and e-commerce. It also offers the Virtuose AI-powered 3D virtual try-on, the patented e-StoreConnect connected display furniture, a sovereign cloud hosting service hosted across three redundant French data centers, managed IT services (infogérance) used by over 3,000 stores, and a training program called Cosium Academy.

Cosium's technology stack is full-stack Java/Angular/TypeScript/Spring Boot/PostgreSQL delivered as SaaS, certified to ISO 27001, HDS v2.0, and ISO 9001, and recognized via the Silmo d'Or 2023 nomination for e-StoreConnect. The platform claims connectivity to 20,000 points of sale and more than 100,000 healthcare professionals across 30 countries, with named customers including Optic2000, Optical Center, Afflelou, Leclerc, Galeries Lafayette Optical, and Acuitis.

Cosium monetizes through annual SaaS subscriptions (quote-based, not publicly priced), managed IT services contracts, hardware sales (Datalogic and Kapelse QR readers, e-StoreConnect furniture), and professional training. Its go-to-market is sales-led via a bilingual commercial team operating from offices in Versailles (HQ), Telford (UK), Barcelona/Madrid (Spain), and Singapore (APAC), supplemented by trade show presence at SILMO and AEDA. The company remains independent, is owned and directed by engineers, and discloses no external investors or M&A activity in the available source material.

Direct peers

• Fittingbox: French-headquartered eyewear virtual try-on platform that directly competes with Cosium's Virtuose product. Both target optical retailers and frame manufacturers with 3D rendering, frame databases, and AR/AI try-on experiences.
• Orisha (Oplus): French software publisher specializing in retail management for optical, fashion, and beauty verticals. Its optical retail offering is a direct French-market competitor to CosiumOptic, targeting the same optician customer base.
• Sycle (GN Group): Audiology practice management system now owned by GN Hearing (a major hearing-aid manufacturer). Sycle is the most direct international competitor to CosiumAudio, serving hearing aid dispensers with patient records, NOAH integration, and billing workflows.
• Eyefinity (OfficeMate): US-based optical practice management and EHR platform owned by VSP Vision. Serves optometrists and optical retailers with PMS, EHR, and frame inventory tools — a directly comparable product to CosiumOptic for the US market.
• RevolutionEHR (Healtharch): Cloud-based optometry EHR and practice management platform serving independent optometrists in North America. Comparable to CosiumOptic in product scope and SaaS delivery model, though oriented to the US regulatory environment.

Broad incumbents

• Cegedim: Major French healthcare technology and BPO company offering practice management, billing, and electronic health-record solutions across multiple healthcare verticals. Represents a broad incumbent that could credibly enter or expand in optical retail software.
• Evolucare: French healthcare software publisher serving hospitals, clinics, and allied health professionals with EHR, imaging, and practice management solutions. Comparable as a French healthcare-IT incumbent with adjacent compliance and hosting capabilities.
• Dedalus: European healthcare IT vendor offering EHR, interoperability, and diagnostic solutions across multiple countries. Relevant as a broad incumbent whose compliance-grade European footprint could overlap with Cosium's HDS-certified sovereign-cloud positioning.
